CRG: Precision Controls Born on the Racetrack
CRG, short for Constructors Racing Group, is one of the most respected names in motorcycle controls hardware. Hand clutch levers, brake levers, handlebar mirrors, and related mounting hardware — CRG designs and builds these components with a singular focus: giving riders the precision and confidence they need, whether on a Sunday morning canyon run or a full-throttle race circuit.
California Roots, Racing DNA
CRG's story began in the late 1990s, when founder Spencer Owyang connected with AMA 600 Supersport Champion Steve Crevier and recognized a real gap in the market: racers needed quality, on-the-fly adjustable brake levers that could be tuned without stopping. That insight led directly to the iconic Roll-A-Click lever — widely credited as the first on-the-fly adjustable motorcycle lever ever produced. Other manufacturers have been attempting to replicate the roll-a-click design ever since.
Today, CRG manufactures its products at a facility in Santa Cruz County, California, situated roughly 30 miles north of Laguna Seca Raceway. That proximity to one of America's most celebrated road racing venues is no coincidence — it reflects the brand's deep ties to the AMA Road Racing community and gives CRG engineers a real-world testing ground to continuously refine their designs.
How CRG Makes Its Products
Every CRG component is produced in-house using CNC (Computer Numerically Controlled) machining processes. The brand relies exclusively on 6061-T6 solid aluminum billets, precision ball-bearing pivots, and stainless steel hardware. The result is hardware that looks great on the bike but is ultimately engineered for function — crisp lever feel, repeatable adjustment, and durability that holds up to track-day abuse and daily street riding alike.
CRG later expanded its lineup to include the industry's first carbon fiber motorcycle brake and clutch levers, offering an even lighter and stronger alternative for weight-conscious riders and racers. The brand's clutch lever assemblies and brake levers are available in a range of lengths — standard, shorty, and folding — and in multiple colors and anodized finishes to match virtually any bike's aesthetic.
Bar-End Mirrors: A Different Kind of Rearward Vision
Beyond levers, CRG has earned serious acclaim for its handlebar mirrors. The Hindsight and Lanesplitter series have become go-to upgrades for sport bike riders who want cleaner bars without sacrificing visibility. CRG bar-end mirrors are among the only CNC-machined mirrors on the market, and their handlebar mirror brackets and adapters make fitment straightforward across a wide range of makes and models — including Aprilia, Ducati, Honda, Kawasaki, Suzuki, Yamaha, and many more.
Trusted by Champions
CRG's products have been trusted and advocated by World Superbike and AMA championship winners — not because of sponsorship optics, but because racers at the highest level demand parts they can genuinely rely on. For street riders, that racing credibility translates to controls and mirrors that feel noticeably more precise and refined than OEM or budget alternatives.
